When connecting a flash drive to my tablet z via a sony usb (host) adaptor it is showing "empty". I've tried different apps with the same result. The USB. Is not empty.
Any ideas?
I should add that I am a complete noobie to android.
Thanks
A number of us have reported problems with storage connectivity via USB. Seems very hit and miss.
You may want to read some of the other threads relating to USB.
Sony have so far been silent On what the problem is. May be you will get a better response.
Thanks, I've been looking everywhere. I will eventually get it to work. 
Try another OTG adapter, another flash drive. Trying many combinations will show you which one doesn't work (OTG most likely) and also give you a combination that works.
It's also possible that the file system on the drive is not recognized by the tablet. Try FAT32 one.
